The 20mm Aluminium Crimp White & White PTFE/Silicone Cap Septa is designed for secure sealing of 20mm headspace and storage vials. It features a white/white PTFE-silicone laminate septum that offers excellent chemical resistance and minimizes extractables, making it ideal for sensitive analytical applications. The PTFE-facing surface contacts the sample, reducing contamination and ensuring reliable sample integrity. The aluminium crimp cap creates a superior leak-proof, evaporation-resistant seal and requires a crimping tool for installation.
